That is cute, & the Toxoplasmosis thing from a veterinary professionals perspective should only affect pregnant sheep, correct me if I'm wrong but those were weaned lambs & following infection sheep are immune and should not abort again due to toxoplasmosis & as long as good vaccination protocols are followed in your sheep & cats are generally kept away from the flocks at lambing times then the risks are minimal. But there are always going to be people who rather have no risk than some, but life's full of them - we just choose which to avoid.
